Valtteri Bottas led the field out at the start of Friday’s second one-hour practice session, although he immediately pitted at the end of his first lap, and remained there for the next 20 minutes as Alfa Romeo worked on his car.
That meant Bottas’ team-mate Zhou Guanyu went through to set the first place benchmark at 1m20.145s, which was quickly beaten by Sebastian Vettel and Lance Stroll – the former having been released into the path of Kevin Magnussen when leaving the Aston Martin garage at the start of the session.
